Great view of Mars.

Mars will be at its closest August 27th, 2003, I recently aquired a mars filter by Televue, made for fantastic viewing of Mars, at the Stellafane astronomers convention in Springfield, Vermont. Features: Optical grade BK7 glass to insure no image degradation due to the substrate. Ion beam deposition of the coatings produces hard, stable coatings to reduce changes due to temperature and humidity.

Mars will be at its closest August 27th, 2003, I recently aquired a mars filter by Televue, made for fantastic viewing of Mars, at the stellafane astronomers convention in Vermont.

I was stunned at the clarity, and the as mars is bright, this filter allowed for detail views unlike I had never seen... I highly recommend this filter!!!! Televue makes a Bandmate Mars Type B filter, a high efficiency, single band dielectric coating that achieves penetrating views of the Martian surface.

The surface appearance is similar to that of the popular #21 filter. However, the Type B features a broadband anti-reflection coating on one side and filter coating on the other that makes it far more efficient.

Features:

Optical grade BK7 glass to insure no image degradation due to the substrate. Ion beam deposition of the coatings produces hard, stable coatings to reduce changes due to temperature and humidity.
Dielectric filter for high transmission and blocking of unwanted wavelengths provide high contrast images. Aluminum filter cells precision machined and engraved.

Televue Mars Filters Type A and B. Just in time for Mars Viewing, for the impressive views these filters offer! Nothing less than fantastic.
